Title: Grape vine or clothes fastening hook - tensioning hook is in form of hanger loop
IPC: F16B2/24
Filed: 1976-01-21
Abstract: In an addition to 2451558 a tensioning hook for attachment of a grape vine or other fruit plant stalks to a tensioned vine support system or even for attachment of washing or clothes to similar tensioned lines has the tensioning hook constructed in the shape of a hanger (118) loop. The hook is of such construction that the growing stem can expand it during its growth and when used for washing considerable safety for attachment of clothes can be ensured. By grape vines are fixture suffices since after one to three years the added growth can be accommodated by either cutting off a piece near the stem or pulling out the loop.
Patent FR-2339475-A1 (FR)
Title: Thermoplastics tube bundles esp. for sewage filter bed - made by fusing together tubes at their ends
IPC: B29C65/02
Filed: 1976-01-29
Abstract: Bonding bundles of thermoplastics tubes to form a grating or lattice comprises firstly fitting the ends of the tubes into a pair of end plates. Each of the plates has, on the face towards the opposie plate, a number of annualar grooves, which join one another at their tangent points. The plates are then heated and pressed together so that the ends of the tubes fited into them fuse together, forming an integral, thickened beading at each end of the tube bundle. If a twist in the final bundle is desired, the annular grooves in one mould plate are slightly offset in the rotational direction from those in the other plate. Method is used for making large numbers of tube bundles for use esp. in biological filters for sewage purification and for water coolers. The tubes are simply bonded together using inexpensive appts. by fusing their ends; thus eliminating the need for manual bonding.

Title: Height and inclination adjustable drawing board - is pin jointed to tops or two vertical columns or which one is telescopic and jack powered
IPC: A47B27/04
Filed: 1976-04-16
Abstract: The drawing board which is adjustable both for height and inclination is mounted on two columns (2b,2c) of which at least one is telescopic obtg. variation in board orientation and height. One of the column (2b) heads is pinned (4) to board gussets (3), and the other column (2c) head attached to the gussets (3) by pin-jointed links (5). The height of the telescopic column may be adjusted by a jack. An alternative arrangement is similar to the above but with both columns (2b,2c) telescopic and jack operated. Generally the columns themselves constitute the jacks with floor mounted fixed cylinders (2b1,2c1) and sliding piston members (2b2,2c2e attached to the board. A further alternative has the columns pinned to the opposite extremities of 'L' shaped board gussets. In this case one of the columns is pin-jointed at both top and bottom.
Patent FR-2313703-A1 (FR)
IPC: F16F1/18
Filed: 1976-06-04
Abstract: A jumper spring for use in a timepiece to releasably hold a toothed wheel comprises a spring member having a generally V-shaped portion engageable with the toothed wheel for releasably holding the wheel during use of the jumper spring, and an elongated arm portion connected to the V-shaped portion. A sputtered layer of chromium covers a part of the V-shaped portion and a sputtered layer of another material overlies the chromium layer. The other material is selected from the group consisting of either a hard material, such as Al2O3, TiC and SiC or a material having a low coefficient of friction, such as MoS2 so as to provide the necessary hardness or low coefficient of friction needed to enable the jumper spring to withstand repeated engagement with the toothed wheel.
Patent FR-2347197-A1 (FR)
IPC: B41J2/51
Filed: 1976-10-20
Abstract: The dot matrix printer is equipped with a selection circuit (1) for several test points, a measurement range selector (2), an analog/digital converter (3) and a storage unit (4) which are controlled by a central processor (7). The storage unit (4) contains storage counters for the measurement values digitised in the analog/digital converter (3). During the transit of the print head (5) over the printing width, several test points are to be covered by a flying calibration. In addition, the print head (5), which can be moved transversely to a recording strip by a stepping motor (9) should record several measurement values during the transit by means of several print pins allocated to the test points. For this purpose, one of the storage counters is allocated to each print pin of the print head (5); furthermore, counting inputs of the storage counters and one control input of a stepping motor control circuit (8) are connected to the output of a stepping pulse generator. Stop signals for the stepping motor (9) and print signals for the print pin allocated to the relevant storage counter are then derived from carry pulses of storage counter bits with the highest significance.

Title: Marine seismic exploration system - has broadband energy source and hydrophone streamer trailed behind ship
IPC: G01V1/38
Filed: 1977-07-22
Abstract: A ship (11) follows a seismic exploration route and surveys an underground formation below a water layer (13). Behind the ship is trailed a cable (17) carrying a linear, horizontal arrangement of seismic energy sources (14, 15, 16,...) and surface floats (18, 19, 29,..).
